Waldo is a beautiful lake, and as long as you go later in the summer - like August and September - the less likely the mosquitoes will drive you back home. It can get quite cold at night, but the cold keeps the mosquitoes down. Tent camping is delightful, especially because generator and motorboat use is quite limited at Waldo. It's a very popular campground, but there's always someplace close by where you can find a secluded spot. When it's really hot, the swimming is lovely - unless the mosquitoes are out. It's a nice place for kids, dogs, and families.
